Hi Everyone,

>From the command line, I'd like to know how to build an exe that links with
a static library with ObjectAda.

Here is the library I want to build.

-- directory structure
    LibCall.adb -- file that calls the library
    Dummy.adb -- dummy file that Withs the library units
    + P_hello
       - P_hello.ads
       - P_hello.adb
    + P_hello_2
       - P_hello2.ads
       - P_hello2.adb

--P_hello2.ads
package P_hello2 is
 procedure hello;
end P_hello2;

--P_hello2.adb
With text_io;use text_io;
package body P_hello2 is
 procedure hello is
begin
  Put_Line("Hello library world 2");
 end hello;

end P_hello2;

--P_hello.ads
package P_hello is
 procedure hello;
end P_hello;

--P_hello.adb
With text_io;use text_io;
package body P_hello is
 procedure hello is
begin
  Put_Line("Hello library world");
 end hello;

end P_hello;

-- Dummy.adb
With P_Hello;
With P_Hello2;

procedure Dummy is
begin
 null;
end dummy;


To build the library I use the following commands

adareg P_hello\*.ad*
adareg P_hello_2\*.ad*
adareg dummy.adb
adamake
adabuild dummy
dir /s /b *.obj > list.txt
lib /out:hello.lib @list.txt
del /q list.txt ada.lib unit.map

Here is the exe I want to build that links with the library.

-- libcall.adb
With P_Hello;
With P_Hello2;
procedure libcall is
begin
 P_Hello.HELLO;
 P_Hello2.HELLO;
end Libcall;


To build the exe I use the following commands

REM registering library search path
adaopts -p.
adaopts -lp .
REM registering source files
adareg P_hello_2\*.ads
adareg P_hello\*.ads

adareg libcall.adb

adabuild libcall -ll hello

And I get the following output:
ObjectAda Special Edition Version 7.2.2: adabuild
    Copyright (c) 1997-2002 Aonix.  All rights reserved.
Front end of libcall.adb succeeded with no errors.
Front end of p_hello_2\p_hello2.ads succeeded with no errors.
Front end of p_hello\p_hello.ads succeeded with no errors.
libcall: Error: Source not found for P_hello2, NO_KIND.  Can't recompile.

libcall: Error: Source not found for P_hello, NO_KIND.  Can't recompile.

libcall: Error: Body not found for P_hello2

libcall: Error: Body not found for P_hello

libcall: Error: Link ended due to previous errors.


Where did I go wrong ?

Any help would be appreciated.
